1) "Scavenger" achievement (Find all of the world map caches) does not work espite getting the perk that reveals all the locations, and checking them all one by one.

2) Technical problems, for example: it keeps asking to set brightness and saturation every time boot up the game. It also randomly launches full screen even though you play it windowed.

3) MAIN PROBLEM - Game saves being deleted/lost. Even if you make numerous staggered saves - but still the game will almost 'forget' all the saves, and revert you to saves you made hours previously. Sometimes when you typed custom titles to saves they'd disappear, but come back after days and numerous boots later.

It looks like that in the Microsoft store in stock is very old version of the W2 DC, which did not receive patches.
Could you fix it?

Second, I was curious what the response was to these issues? I have owned the game forever but could never make progress due to the save games disappearing, and I'd love to see that glitched achievement get fixed as well.
